TL;DR: The Sloan Digital Sky Survey (SDSS) as discussed by the authors provides the data to support detailed investigations of the distribution of luminous and non-luminous matter in the universe: a photometrically and astrometrically calibrated digital imaging survey of π sr above about Galactic latitude 30° in five broad optical bands to a depth of g' ~ 23 mag.

TL;DR: In this paper, the relation between stellar mass and gas-phase metallicity was studied using the Sloan Digital Sky Survey imaging and spectroscopy of ~53,000 star-forming galaxies at z = 0.1.

TL;DR: The Sloan Digital Sky Survey (SDSS) is an imaging and spectroscopic survey that will eventually cover approximately one-quarter of the celestial sphere and collect spectra of ≈106 galaxies, 100,000 quasars, 30,000 stars, and 30, 000 serendipity targets as discussed by the authors.

TL;DR: In this article, a variety of composite quasar spectra using a homogeneous data set of over 2200 spectra from the Sloan Digital Sky Survey (SDSS) was created, and the median composite covers a restwavelength range from 800 to 8555 A and reaches a peak signal-to-noise ratio of over 300 per 1 A resolution element in the rest frame.

TL;DR: In this paper, the 158 standard stars that define the u'g'r'i'z' photometric system are presented, which form the basis for the photometric calibration of the Sloan Digital Sky Survey.
